These words are nearly the same as the version in the DT, but that transcription has several major shortcomings: it doesn't identify which part is the chorus; it doesn't indicate where the chorus is to be repeated; it doesn't explain how the chorus changes from one verse to the next; and no source or author is credited.

Transcribed by me from the sheet music at The Library of Congress American Memory Collection, with punctuation added.

CASEY JONES
(Words, T. Lawrence Seibert. Music, Eddie Newton. Copyright 1909.)

Come, all you rounders, if you want to hear
A story about a brave engineer.
Casey Jones was the rounder's name.
On a six-eight wheeler, boys, he won his fame.
The caller called Casey at a half past four,
Kissed his wife at the station door,
Mounted to the cabin with his orders in his hand,
And he took his farewell trip to that Promised Land.

CHORUS: Casey Jones! mounted to the cabin.
Casey Jones! with his orders in his hand.
Casey Jones! mounted to the cabin
And he took his farewell trip to that Promised Land.

"Put in your water and shovel in your coal.
Put your head out the window. Watch them drivers roll.
I'll run her till she leaves the rail,
'Cause I'm eight hours late with that western mail."
He looked at his watch and his watch was slow.
He looked at the water and the water was low.
He turned to the fireman and he said,
"We're going to reach Frisco but we'll all be dead."

CHORUS: Casey Jones! going to reach Frisco.
Casey Jones! but we'll all be dead.
Casey Jones! going to reach Frisco.
We're going to reach Frisco but we'll all be dead.

Casey pulled up that Reno Hill.
He tooted for the crossing with an awful shrill.
The switchmen knew by the engine's moan
That the man at the throttle was Casey Jones.
He pulled up within two miles of the place.
Number Four stared him right in the face.
Turned to the fireman, said, "Boy, you'd better jump
'Cause there's two locomotives that's a-going to bump."

CHORUS: Casey Jones! two locomotives.
Casey Jones! that's a-going to bump.
Casey Jones! two locomotives.
There's two locomotives that's a-going to bump.

Casey said just before he died,
"There's two more roads that I'd like to ride."
Fireman said, "What could that be?"
"The Southern Pacific and the Santa Fe."
Mrs. Jones sat on her bed a-sighing.
Just received a message that Casey was dying.
Said, "Go to bed, children, and hush your crying,
'Cause you got another papa on the Salt Lake Line."

CHORUS: Mrs. Casey Jones! got another papa.
Mrs. Casey Jones! on that Salt Lake Line.
Mrs. Casey Jones! got another papa,
And you've got another papa on that Salt Lake Line.

[The Water Valley Casey Jones Railroad Museum seems to have the most thorough and reliable information about the real Casey Jones, and the early history of the song.]
